OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 738,635, dated September 8, 1903.

Application filed December 27,19'o 2. Serial No, 136,794. (No model.)

To all whom it may concern:

Be it known that I, CHARLES WILLIAM SIE- .VERT, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

This invention relates to an oil-burner constituting to some extent an improvement over my priorpatent, No. 710,899, dated October 7, 1902.

The object of the present invention is to effect a more thorough and uniform'vaporization and consequent combustion of the oil and also to enable the burner to be placed in any desired position'and supplied with oil in company with a relatively thinjstr'eam of water, which effects thorough atomization of the oil and also when heated assists in transforming it into vapor.

This specification is an exact description of several forms of the invention, While the claims define the actual scope thereof.

. construction here illustrated, of two sections Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view showing one form of the invention.

vention.

Referring to Fig. 1, a indicatesthe casing. of a stove,.which is here illustrated as of the round or cylindrical type. It may be either a cooking or heating stove. In this stove is placed a base plate made up, according to the and from the section b of this base an air-pipe d passes upward, thence inward and'downward, so as to discharge the air into. an oilcup 6. Said oil-cup is formed with a conef in the bottom thereof, and on this cone are produced a number of annular ridgesf,forming shallow pockets for the oil and allowing a more intimate association of the oil with the burner.

9 indicates an oil-pipe, and It indicates a water-pipe, said pipe gextending through the Fig. 2 is a vertical section thereof, and .Figs. 3 and 4 are secg tional views showing other forms of the inwater-pipe h and discharging slightly above the upperend thereof.

In the use of this invention the oil is first introduced into the cup 6 and a small quan' tity burned to give the burner its initial heating, after which the oil and water are introduced in the proper proportions, and upon striking the heated surfaces of the parts f and c the oil Will be instantly converted into vapor and burned just below the mouth of the pipe cl, this pipe supplying oxygen meanwhile to support combustion.

Fig. 3 illustrates a form of the invention in which the Water-pipe h and oil-pipe g instead of being passed upward through the conef of the oil-cup c are passed centrally through the air-pipe and discharged downward onto the conef in the same direction that the air is discharged.

Fig. 4 illustrates the same construction shown in Fig. 3, excepting that the air-pipe d is more of the form shown in my prior patent referred tothat is to say, this pipe is of inverted- U shape, its lower end passing through the base-plate c and its middle portion being formed with a downwardly-dis posed branch (1 which discharges directly onto the conefof the oil-cup 6.

Various other changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An oil-burner, comprising a base or support, a burner-pan thereon, a cone placed in said pan, an oil supply pipe passing up through the cone at the apex thereof, means for supplying a current of air above the cone, and a water-supply pipe inclosing the oil-supply pipe and extending upward through the cone, said oil-supply pipe and Water-supply pipe discharging simultaneously at their upper ends.

2. An oil-burner, comprising the combination with a base or frame, of an oil-cup, a coneplaoed therein and formed with a number of annular ridges on its outer surface,

an air-supply having its discharge directed downwardly over the cone, means for supplying oil to said cone, and means for supplying water to the cone simultaneously with the oil, said oil and water supply means comprising tubes extended the one through the other, and said tubes having their discharge ends located adjacent to the apex of the cone.

3. An oil-burner, comprising a base or frame, a burner pan or cup thereon, a cone placed in said pan and formed with a num her of exterior ridges, an oil-supply pipe passing up through the cone to the apex thereof, a water-supply pipe also passing up: through the cone to its apex, said pipes ex-' tending one through the other and means for,

supplying a current of air to the cone.

4. An oil-burner, comprising a base or frame, a burner pan or cup thereon, a cone? placed in said pan and formed with a numher-of exterior annular ridges, an oil-supply passing up through the cone to the apex thereof, a water supply also passing up through the cone to its apex, and means for supplying a current of air downward onto the cone, the said oil and water supply comprising pipes passing the one through the other and discharging at their upper ends.

5. An oil-burner, comprising a base or frame, a cup placed thereon, a cone placed in the cup, an air-supply pipe extending from below the base upward and curved over and downward to discharge downward onto the cone, and oil and water pipes run the one through the other and passed upward through the cone to the apex thereof.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
